Pemko EXT2D36 36" 3' x 2" Extender for All Residential Sills Dark Bronze Anodized Aluminum Finish

The EXT2D36 threshold extender bridges gaps between existing residential door sills and flooring surfaces. This 36-inch aluminum extension piece installs at door openings to create proper weatherization and eliminate air infiltration problems. The extender solves common issues where original threshold installations leave exposed gaps that allow drafts, moisture, and energy loss.

Pemko manufactures this extender from anodized aluminum with a dark bronze finish that resists corrosion and wear. The 2-inch width provides adequate coverage for most residential gap scenarios. Mounting hardware comes included for straightforward installation on concrete, wood, or metal substrates.

This extender complements door assemblies that must meet energy codes but does not carry specific fire or life safety certifications. For installations requiring NFPA 101 Life Safety Code compliance on egress doors, verify that threshold modifications maintain required exit widths and accessibility clearances. When weatherizing doors that also need UL 10C fire ratings, ensure any threshold work preserves the fire door assembly's listing integrity.
